Title:
perf top error: "The cycles:P event is not supported" on 13th gen /
raptor lake
Status in linux package in Ubuntu:
Confirmed
Bug description:
`perf top` immediately fails to start for me, 6.5 on i9-13900kf, with
the error: The cycles:P event is not supported.
`perf record` and `perf stat` appear to work fine, including `perf
stat` showing the two different sets of counters for cpu_core and
cpu_atom.
Looking at strace, it appears that `perf top` is fails to fallback to
lower fidelity events on the "efficiency" cores (16+ for me), while
this process happens automatically for `record` and `stat`.
`perf top -C0` (which should exclude the efficiency cores) and `perf
top -e cpu_core/cycles/` (which should also exclude the efficiency
cores, as I understand the docs) seem to fail in the same way.
top's retry has a higher `sample_freq`, `mmap`, `comm`, `mmap2`,
`comm_exec`, `ksymbol`, and `bpf_event`, but the reduced precise_ip
it's trying for, and still gets an EINVAL.
